If a body is uniformly accelerated, then it's velocity is changing by equal amounts in equal times. Suppose you drop a lead ball from a high tower. At the moment you drop it, its velocity is zero and it accelerates to 10 metres per second in the first second. In the fifth second for example it accelerates from 40 m/s to 50 m/s. The acceleation is ten more metres per second over each second. That is a constant acceleration. A steadily increasing velocity.
In real life, the falling ball would not have constant acceleration because the faster it falls, the greater is the air resistance which tries to slow it down. If the ball falls from a high enough tower, its speed will become almost constant because the air resistance force upward will be close to the weight force downward and the acceleration will disappear. The ball reaches "terminal velocity".
Linear motion is motion in a straight line, no sideways disturbances.

Why uniform circular motion is an example of accelerated motion?
Because 'acceleration' does NOT mean 'speeding up'. It means any changein speed or direction of motion.Uniform circular motion involves constantly changing direction, and that'sconstant acceleration.
What does uniform linear motion mean?
An object in free space when set in motion continues to be in motion indefinitely in a straight line, if it is not influenced by any other force [or energy]. When the rate of change of position with respect to time is constant, then this motion is called UNIFORM LINEAR MOTION. An everyday example of linear motion is the soldiers marching past in a parade. Other examples of linear motion are a car moving at a constant speed, a bullet fired from a pistol moving towards the target, etc.
Does a car accelerate in circular motion?
Anything in circular motion is accelerated.'Acceleration' does NOT mean 'speeding up'. It means any change in the speedor the direction of motion.Circular motion involves constantly changing direction, and that's constant acceleration.
Why is motion of satellites around earth is considered an accelerated motion?
Accelerated.ALL mass in the universe is constantly being accelerated by gravitational forcesfrom every other mass in the universe. Specifically, a satellite in orbit is constantly fallingtoward the Earth under gravity - but because of the inertia of the satellite, it is continuallymissing the Earth! In the absence of gravity, the satellite would proceed in a straight linetangent to its current elliptical orbit.And now, after that refreshing interlude, here is the answer to the question:"Acceleration" does not mean "speeding up".It means that either speed or direction is changing, (or both are changing).Anything that's not moving in a straight line is in accelerated motion, becauseits direction is changing.A satellite is certainly not moving in a straight line.Therefor its motion is accelerated.
Is the motion of the tip of the second hand of a clock equal to the motion of the entire second hand of the clock?
What do you mean with "motion of the entire second hand"? Please bear in mind that different parts of the hand move at different speeds. The closest thing to a "motion of the entire second hand" might be the motion of its center of mass. In this case, the answer is clearly "no". The center of mass is closer to the center than the tip, and moves slower.

Differences between the mean and median filter?
Mean filtering is linear but median filtering is non-linear.
Why earth has no acceleration?
The Earth has a huge amount of acceleration ... but that word doesn't mean"speeding up". It means any change of speed or direction of motion. Since theEarth revolves in a closed, curved path around the sun, it's constantly changingits direction of motion. So it's constantly accelerated.
